Abstract

The invention discloses a high-flame-retardancy rubber material for cable sheaths, which is prepared from the following raw materials in parts by weight: chloroprene rubber, chlorinated polyethylene, styrene-butadiene rubber, zinc oxide, stearic acid, dibasic lead sulfate, tribasic lead sulfate, lauric acid, pentaerythritol, epoxy soybean oil, purple carbon black, attapulgite, carbon black, a coupling agent, modified hazelnut oil, magnesium oxide, antimony trioxide, chlorinated paraffin, decabromodiphenylethane, a charring agent, ammonium polyphosphate, sulfur, a vulcanizing agent DCP, an anti-aging agent MC, an anti-aging agent 4010Na, an accelerator DM, an accelerator CZ and an accelerator NA-22. The modified hazelnut oil is prepared by the following steps: adding hazelnut oil, acetic acid and an ion exchange resin into toluene, stirring and heating to react, dropwisely adding an oxydol solution, reacting at 60-70 DEG C for 8-10 hours, and collecting the oil phase. The high-flame-retardancy rubber material for cable sheaths has the advantages of high flame retardancy, higher elasticity and higher strength.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a high flame-retardant rubber material for cable sheaths. Background technique [0002] With the development of the electric power industry, the competition in my country's wire and cable market is becoming more and more fierce. Cables can be divided into power cables, communication cables and control cables according to their uses. At present, it has been used in many fields, such as wind power generation, ships, etc.; cables generally include conductive cores, insulating layers, sheaths and protective coverings. The sheath is an important part of it, and the material used for the sheath should have high insulation, flame retardancy, high breakdown electric field strength, low dielectric loss and low dielectric constant. [0003] Neoprene has high flame retardancy, excellent tensile strength, weather resistance, oil resistance, and chemical corrosion resistance, and can ...
